Official data shows that since 1953’s Hillary-Norgay summit, around 9,000 mountaineers have successfully scaled Mt Everest while over 300 have lost their lives.

Nepal will issue Everest permits only to climbers with experience of scaling at least one of the Himalayan nation’s 7,000-meter (22,965 ft) peaks, according to the draft of a new law aimed at reducing overcrowding and improving safety.
